Title: Extraction of silica and magnesium compounds from olivine
Inventor: HANSEN TORD
IPC: C22B3/08
Filed: 2001-10-29
Abstract: A method is described for extraction of silica and magnesium compounds, by chemical and thermal treatment of the mineral olivine. The method comprises sulphating of olivine, where olivine is mixed with concentrated sulphuric acid at a weight ratio olivine/sulphuric acid of approx. 0.5-0.67, and by heating the mixture to approx. 250 DEG C and giving the mixture a reaction time of approx. 8 hours, and thereafter dissolve the mixture in water, whereby silica percipitates to a solid and where the silica after filtration is purified in a weak solution of soda, and eventually with a weak aqueous solution of an acid or a mixture of acids. This method provides manufacturing of a purified silica solid, leaving a filtrate consisting mainly of dissolved magnesium which after further processing is transformed to magnesium compounds.

Title: Axial gradient transport apparatus and process for producing large size, single crystals of silicon carbide
Inventor: SNYDER DAVID W
IPC: C30B29/36
Filed: 2001-03-13
Abstract: Disclosed is an apparatus and a method for growing single crystals of materials such as silicon carbide through axial gradient transport. A source of the material (10) is placed at one end of a reaction chamber (2) opposite a seed crystal (13). Separate heating elements (16 and 60; 20 and 62) are positioned at opposite ends of the reaction chamber. The reaction chamber (2) is placed in a growth chamber (26). By appropriately controlling the vacuum in the growth chamber (26) and the temperature of the heating elements (16, 20), including the temperature differential therebetween, a uniaxial temperature gradient is generated in the reaction chamber (2). In this manner, planar isotherms are generated and a high quality crystal can be grown through a physical vapor transport process.

Patent WO-8902534-A1 (WO)
Inventor: GRZINA ANTHONY
IPC: F04D29/42
Filed: 1988-09-15
Abstract: A liner for a centrifugal pump of the type made from wear resistant metal is conventional made with a step (5) in the inner surface of the liner between the junction of the side liners (2 and 3) and the volute liner (1), because of the difficulty in machining the hydraulic surface of the liner. This step (5) causes localized accelerated wear. The liner of the present invention is made with a thickening (11) of the area adjacent the joint with the side liners (2 and 3) which thickening protrudes inwardly beyond the inner surface of the side liners (2 and 3). Upon assembly the thickening (11) is reduced to align with the inner surface of the side liners (2 and 3), to reduce localized wear on the liner.

Title: Ion-conducting sulfonated polymeric materials
Inventor: MCGRATH JAMES E
IPC: C08L81/06
Filed: 2001-09-20
Abstract: Sulfonated polymers are made by the direct polymerization of a sulfonated monomer to form the sulfonated polymers. The types of sulfonated polymers may include polysulfones or polyimides. The sulfonated polymers can be formed into membranes that may be used in proton exchange membrane fuel cells or as ion exchange membranes. The membranes formed form the sulfonated polymers exhibit improved properties over that of Nafion3. A heteropoly acid may be added to the sulfonated polymer to form a nanocomposite membrane in which the heteropoly acid is highly dispersed. The addition of a heteropoly acid to the sulfonated polymer increases the thermal stability of the membrane, enhances the conductivity above 100  DEG C, and reduces the water uptake of the membrane.

Filed: 1998-11-24
Abstract: On effectue le dépôt de couches de silicium amorphe hydrogéné simultanément sur deux substrats métalliques ou diélectriques (25, 26, 43, 44) à partir d'une décharge luminescente haute fréquence (32) maintenue dans un mélange de gaz ou de vapeurs dont au moins un de ces derniers contient du silicium dans sa molécule. On maintient la décharge (32) entre deux électrodes (20, 21, 41, 42) présentant une symétrie réciproque, alimentées en haute fréquence, enfermées dans une chambre mise à la terre (22, 40) et isolées de celle-ci, un substrat étant placé sur le côté intérieur de chacune des électrodes (20, 21, 41, 42). Toutes les surfaces des électrodes (20, 21, 41, 42), à l'exception des deux surfaces sur lesquelles les substrats (25, 26, 43, 44) sont placés, sont enfermées dans des pièces métalliques (28) mises à la terre, dont quelques unes peuvent être des parois de la chambre et entre lesquelles un espace suffisamment limité sert à empêcher la création de décharges aux pressions du processus. Ce procédé peut être augmenté, de manière à effectuer un dépôt simultané sur 2n (n = 1, 2, 3) substrats dans chacune de n paires d'électrodes, au moyen, par exemple, d'un dispositif de revêtement à plat particulièrement bien adapté à la configuration de la cathode creuse.
